AA/(EPA + DHA) ratio in the milk of CON‐, WD‐, and REV‐dams at lactation days 5, 10, and 15 a), and in the plasma of their male and female offspring at postnatal day 15 b), and mRNA expression of anti‐inflammatory (adiponectin) and pro‐inflammatory (TNF‐α, IL‐6, and COX‐2) factors in the mammary gland of dams at the end of lactation (day 21) (C). Data are mean ± SEM (n = 6–10). Statistics: one‐way ANOVA followed by a LSD post hoc test was performed to determine differences between groups, and Mann–Whitney U test was used for single comparisons. Symbols: a ≠ b ≠ c (p < 0.05, one‐way ANOVA); *different from CON‐dams (p < 0.05, Mann–Whitney U test). AA, arachidonic acid; ANOVA, analysis of variance; CON, control; DHA, docosahexaenoic acid; EPA, eicosapentaenoic acid; LSD, least significant difference; REV, reversion; SEM, standard error of the mean; WD, western diet.
